SPEOIFICATION forming part of Letters, Patent No. 761,729, dated June 7, 1904.

' Application filed September 5,1903. Serial No. 172,120. (No model.)

To all whom it mayconc'ern:

Be it known thatwe, JOHN MESNY TOURTEL and GEORGE L wIs HOGAN, both citizens of the United Kingdom of Great Britain and Ireland, and. residents of London, England, have invented certain new and useful Improvements in Phonographs and the Like, of which the following is a specification, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and specifically claimed.

We will now describe our invention with reference to the accompanying drawings, in which- Figure 1 shows in side elevation a phonograph or talking-machine constructed according to our invention. Fig. 2 shows an enlarged view from the top of the mouth of the trumpet and shows the slot in the flange and the means for adjusting the same. Fig. 3 shows a view in section of the joint between the celluloid body of the trumpet and the metal mouthpiece. Fig. 4 shows an enlarged view of the center of the combination-bracket for supporting the trumpet. Fig. 5 shows an end View of the combination-bracket and shows the rod fitting into the hinged ferrule on the mouth of the trumpet. Fig. 6 shows a view, partly in section, of the apex of the trumpet and shows the flat spring and its connection to the trumpet and to the stylus. Fig. 7 shows a plan view of Fig. 6 as seen from above. Figs. 8 and 9 are respectively front and edge views in elevation of one form of flexible stylus.

a is the celluloid body of the trumpet, havingflange a along its side.

I) is the mouth of the trumpet, formed with flange 0, on which are metal lugs at each side of ithe slot 6, said lugs being he (1 to each other by thumb-screw d.

e is t 1e hinged ferrule on the m uth b.

f, g, h, and 2' are respectively the bent rod, the short bar. the set-screw, and the arm forming the bracket for the trumpet.

7' is the cabinet of the machine, with usual spring driving mechanism Z.

Z is a light spiral spring attached at one end to the ferrule e and at the other end to the flange c. The spring is for the purpose of exercising the necessary downward, pressure of the apex of the trumpet.

The foregoing need not, it is thought, be further described in detail, since the parts are illustrated and described for the purpose of showing the application of our invention in certain relation to parts of a phonograph.

mis the usual disk record in which the soundwriting is made.

a is the cap on the apex of the trumpet and covers plugn, into which is screwed bar'p, carrying lock-nut 0, and to which bar isfixed one end of the spring 7, the other end terminating in the stylus-holder r, in which is fixed stylus s.

0' is a washer between the lock-nut 0 and the plug 17/.

In Figs. 8 and 9 the stylus s is flattened at 8.

It is obvious that other means besides a flexible flat spring may be provided to eifect the purposes herein set forth, and in accordance with our invention we may construct in other ways than those previously described a-stylus or stylus-support, or both,'flexible in one direction to a sufficient extent to render it or them useless as a conductor of sound-vibrations from motion in that direction and effective as a conductor of vibrations corresponding to sound-writings from motions in another approximately normal direction.

What we claim, and desire to secure by Letters Patent, isv 1.. In a phonograph, a trumpet, a plug in the apex thereof, a rod threaded in the plug, a nut threaded on the rod and adapted to abut the apex of the trumpet for holding the plug in contact with the trumpet.

trumpet, a stylus and means connected to the plug for carrying the stylus.

In witness whereof we have hereunto set our hands in presence of two witnesses.
